Megaformer as a Rehabilitation Modality for Hamstring Strain Injury in Division I American Football: A Case Study

BACKGROUND: With athletes striving for peak performance, noncontact muscle strain injuries are increasingly common. Hamstring strain injuries (HSIs) make up the largest portion of noncontact injuries and provide further difficulty because of the high reinjury rate. This case study explores the Megaformer as a modality to treat HSIs with the potential to reduce the return-to-play timetable and recurrence rate. CASE PRESENTATION: A 23-year-old male American football player with a history of hamstring injuries presented with pain in the right proximal hamstring and deficits in strength and mobility testing as a result of sustained hyperflexion of the right hip with full knee extension. Magnetic resonance imaging confirmed a recurrent proximal hamstring strain. OUTCOME AND FOLLOW-UP: Subsequent strength and range-of-motion testing revealed no impactful tenderness or pain during active participation or palpation after 9 days, and complete alleviation of symptoms at 6 weeks. No reinjury occurred during the remaining football season. DISCUSSION: This case study highlights possible advantageous features of the Megaformer as a recovery modality for HSIs. The Megaformer aims to improve flexibility, strengthen primary and secondary muscles, and enhance neuromuscular coordination to attempt to decrease the return-to-play timetable and reduce injury recurrence.
